edk2: update to edk2-stable202608

Update edk2 and edk2-platforms from edk2-stable202605 to edk2-stable202608 tags.

Add a backport for the SmbiosType2Generator clang build failure
introduced by the newer edk2 release.

Remove the same patch from RDN2 and RDV2, where it is not
applicable because those platforms use an older SHA-based edk2
release.

Update SBSA-ACS to use the new edk2 release.

+Subject: [PATCH] DynamicTablesPkg: fix SmbiosType2Genertor build failure with
+ clang
+
+BaseboardCount type is UINT32. Using MAX_UINTN in the comparision
+triggers below build error:
+
+  type 'UINT32' (aka 'unsigned int') is always false
+    [-Werror,-Wtautological-constant-out-of-range-compare]
+  199 |       (BaseboardCount > (MAX_UINTN / sizeof (*CmObjectList))))
+
+To address this, use MAX_UINT32 instead of MAX_UINTN.
